My invention relates to barb-fence machines for manufacturingtwo-pointed, double-strand, nudt'wistedbarb fence-wire; and it consistsin the combination of mechanism hereinafter described for producingfinished barbed fencewire having short barbs by acontiuuous andautomatic operation.

have invented certain new and useful improveimprovements. All of thesucceeding figures,

larged scale from that shown in Fig. 1,-except ofthe lessimp'ortantparts broken oft and shown. in Figs. 2 2, for the purpose of moreclearly.

and cam Q, the latter being To enable those skilled in the art to whichmy invention belongs to makeand use the same, I will proceed to describeit more in detail.

1n the drawings 0 represents the bed-plate of the machine, whfichissupported at each end on suitable frames or legs, D, and cut away atthe points E to receive portions of the machine extending below the topsurface.

Upon the bed 0 are formed or secured the bearings F F for the maindriving-shaft G to turn in, the bearings H H. H for the shaft I, thebearings J J J for the shaft K, and the bearings L L L for the shaft M.

To one end of the main driving-shaft G is secured a bevel-gear, G, whichengages with a smaller bevel-gear, G secured to the end of shaft G,.which turns in the stationary bearings G G. To the other erid of saidshaft G3 is secured the driving-pulley N, which may be connected by abelt With'any suitable and convenient driving mechanism. Upon the otherend of the main driving-shaft G is secured a circular disk, 0, andbetween the latter and bevel-gear G a bevel-gear, P, collars Q Q, Qshown by dotted lines in Fig. 5. i

Driving-power is imparted from shaft G to turn shaft M (upon which thelower main wire feed-rolls, R R, are arranged and secured) by means of alink or pitman, S, secured at one end to a crank-pin on the outer sideof the circular disk 0, and at its'other end to the outer end of acrank-arm, S, which is loosely con nected at its other end to the end ofsaid shaft M. i i

The shaft R of the upper feed rolls, R R,

.isarranged; to turn in verticaily slidin g bearings B R ,.and saidrolls are operated by the J lower. ones by means of spur-gears B 3secured upon the shafts M and R between each set of feed-rolls, as shownin the drawings.

standards It, between said bearings R and bearings L. The upper feedrolls, R are forced down, so as to produce a pressure upon the mainwiresto feed the latter forward by turning'eccentric R by means ofhandle R", so as to bear down on the top of bow-shaped spring R arrangedon top of the bearings R of said feed-rolls B. The spring R is in thisinstance held in position upon the bearings R by means of pins 1 g, andis made with a slot, h, at one end to admit of the upper feed-roll beingsprung up sutticientto allow bunches or other imperfections on the wiresto pass between the rolls withoutinjury tothe same. The feedrolls R Rare given an intermittent rotary motion, so as to feed the main wiresforward at intervals when required, as hereinafter described, by meansof a ratchet-wheel, t, and pawl j, the pawlj being hinged to thecranklever S at j and held against the ratchetwheel, so that it willcatch against the notchesk by means of a spring, 7;. By thisarrangementit will be seen that when the lever S is moved forward by therotation of 'disk 0 the. pawl is forced up and turns the ratchet-wheeland shaft M, and consequently the feed-rolls,

to feed the main wires forward. The eccentric R is pivoted at the centerto cross-frame piece R", which is fastened at each end to the tops ofstandards R R In practice the several parts are so constructed andarranged in relation to each other as to turn the feed-rolls asufficient distance to feed the main wires forward the distance requiredfor the barbs to be secured apart upon the same which in practiceisusually about four inches.

In order that the feed-rolls It R may be prevented from turning too farafter feeding the main wires forward, and thereby disar-- ranging theirdriving mechanism, a ratchetwheel, I, is arranged and secured upon shaftM, next to one of the bearings L, and a pawl or dog, m, (pivoted at m toa stationary standard, m5) is arranged 'to catch against one of, thenotches, l, of said ratchet wheeljust as the pawl j recedes from itsnotch onthe ratchet-wheel 1'. Were such a provision not made, thetension produced upon the two main wires by the twisting operation,hereinafter referred to, would tend to move the rolls and theiroperating parts so far forward as to cram p or retard the proper actionof the same.

The pawl m is held down so as to catch against the notches l of theratchet-wheell by means of a spiral spring, n, fastened at one end tothe under side of said pawl m and at the other end to a stationary part,a, and is raised at the proper time to allow the notches to pass by theend of the pawl m by a cog or tooth, n formed upon collar Q, (see dottedlines, Fig. 3,) striking the rear curved end, a of said pawlm as theshaft Gr revolves.

The several parts are so constructed and arranged in relation to eachother as to feed the main wires forward the distance between one barband the next succeeding one at each revolution of the main driving-shaftG. Driving-powerisimparted from said main drivingshaft to turn shaft 1by means of the bevelgear P, which engages with a similar bevel.- gear,1?, upon the end of said shaft 1.

The barb-wire feed-rollsT T and their actu: ating mechanism aresimilarlyconstructed and arranged in relation to said shaft I as themain wire feed-rolls are to the main drivingshaft G, a circular disk, T(see Figs. 2, 2, and 4,) being secured to the outer end of the shaftLwhich is connected to a crank, T, on the outer end of the shaft Ktuponwhich the lower barb-wire feed-roll is secured) by means of a longpitman or connecting-rod, T, the shaft of the upper feed;roll, T, beingalso fitted to slide upand down on vertical'standards T T said rollsgiven a springing movement by means of spiral springs T T", bow-spring Tand eccentric T", and are operated by the lower roll, T, by means ofspur-gears T -T Said feed-rolls are also given an intermittent forwardrotary motion, the same as the main wire feed rolls, by means ofaratchet-wheel, K and pawl K A similar device to that before describedfor governing the turning of the main wire feedrol ls is also providedfor the barb-wire rolls T T to prevent the-tension upon the wire (causedby coiling the barb wire around the main strand to form the barbs, ashereinafter do scribed) from turning said rolls too far forward 'for thereason before stated.

In this instance a ratchet-wheel, T is fastened upon the inner end ofthe shaft K, against the side of the inner bearing, J, and its pawl T'-is fastened upon the end of a shaft. T, which is fitted to turn instationary bearings T T and provided with the enlarged end- T extendingat right angles to the same, over the collar Q upon shaft Gr, which isprovided with a cog or tooth,T for raising the pawl of the ratchetwheelat each revolution of said shaft G above and out of action with thenotches 0 when required. The weight of the enlarged end T is suflicientin this instance to hold the pawl rocking segment-gear-part, W,(fulcrumedupon a journal, W, arranged in the tops of standards W W2) afriction-roll, W being fitted to turn on a stud,p, in the outer end ofthe rocking part W, over the cam, against which said cam bears whenrotated, thus irnparting its action to the rocking part, as abovedescribed. .The inner end of said rocking part W is provided with asegment spur-gear, W

which'engages with a pinion, W secured upon a journal, W fitted to turnin the stationary bearings W W. The bearing W is extended'up; to form along bearing for the IIC journalaspiuion W and pinion W formed" upon orsecured to the end of spindle W Said spindle W is fitted looselyinitsbearing longitudinally, being prevented from moving in the directionfrom the pinion W by said barb coiling. or wrapping spindle W and saidspindle is operated by the rockingpart W through the aforesaidsegment-gear W pinion W spur-gear W (secured upon thesame pinion bearingagainst the side p of bearing W, and in the opposite direction byaspring, W secured at p to the bearing W. This arrangement admits of thespindle being sprung backward slightly, as' required, bythebarbcoilingoperation hereinafter described, which is a very essential feature, aswill be seen, to properly coil the barb-wire around the main wire.

.In coiling the barb-wire at around the main wire as it is first fedforward under said main wire and over the turning-fingerq of the wrapping spindle W when said spindle W is then turned in the direction ofthe barb-w-irefeed rolls T T, as shown by arrow M, Fig. 10, by

wire to form the barbs m in the following manraising the outer end ofthe rockingpart W, as before described, and thereby coiling or wrappingthe barb-wire around the m ain wire, as represented at 00 Figs. 11 and12 of the drawings. i

The cam U is made of the propershape to turn the spindle W9, so as toform two coils, as shownfabout the main wire 00,, and to afterwardreverse or turn back said spindle into itsoriginal position, as shown"in Figs. 2, 3, andet of the drawings, at each revolution of camU,whichlis turned with the same speed as the main driving-shaft Gr.

As the barb-wire wiscoiledaround the main wire 00 toward the wrapping-spindle W it bears against and forces said spindle and its spring W'back, thus producing quite apressure upon the coil as itisformed,whichinsures a compact and perfect finished coil. 7

The cam U is so formed, as will be seen by Figs t and 10, that thespiral springVcanses the wrapping-spindle to very quickly recede or turnback into its originalposition after forming'the coils, as beforedescribed.

After the barb-wire 00 has been coiled about the main wire 11;, asbefore described, said wire is cutoff upon an anglecl'ose up to saidmain ner: v

A stationary cutter, s, is arranged in the top of an angular stationaryblock, X, said block being cut out, as shown at t, toreceive' it. Saidcutter s isheld in place by the side plate, t, andtop plate, t and maybeadjusted longitudinally by means of the set screw t whichmay be turnedforward or back in the it part cor block X, sufficient space being al-,

lowed between the end of the cutter and the part to admit of theaforesaid adjustment.

, The inner end of cutter s is made upon an angle laterally, and itsupper edge, e, is made a sharp cutting-edge. V (See Figs. 2, '6, and 9.)

part's X X of stationary block X. By

The movable cutter u is arranged and fastened in the top of the angularrocking part Y,

which is pivoted obliquely to the line of the main wire, and also to thelineof the barbwire, at its inner end, upon pointed screw-studs Y Y,that are fitted to turn is and out in the this arrangement it will beseen that the movable cutter a may be adjusted laterallyto the stationary cutter s by simply turning set-nuts Y Y and moving thepivot-screws Y Y as required.

The movable cutter supporting and rocking part Y is pivoted at itsforked end or head obliquely to the spindle W and to theline ofthefence-wire, so that when its outer end israised the movable cutter u ismoved forward and laterally by the end of the spindle W and to-' wardthe main fence-wire, so as to cut off the barb-wire close up tothe mainwire. The axis upon which the support for the movable cutter turns isoblique to the axis of thebarbwire feed-rolls, so that the said cuttermoves obliquely across the barb-wire, and, in virtue" ofthe obliquity,has a shear or drawing out on the wire. f

New portions of the cutting-edge will suecessively come into action, themotion of the moyable cutter being the resultant of two niotions-oneparallel with the cutting-edge and one perpendicular thereto--ot' whichmotions the former has the effect of bringing succesupon its under side,and the rocking partY isso operated byineansof the cam Q (see dottedlines, Fig.5) as to cause the movable cuttingedge a to be moved forwardby and in close contact with the stationary cutting-edge s to cut on thebarbwire, as hereinafter described. The cam Q is secured upon the maindrivingshaft G,directly under the rearend, Y, of the rocking'partY, andsaid part Y ispivoted'at a considerable distance below the level of thesaid forward movement of the movable cutteru.

It will be observed by Figs. 2 and. 6 that the 1 2o stationary cutter s,so as to admit of the aforestationary cutting-edge s is arranged aboutin the vertical plane through the centers of the pivotal bearings of therocking part, thereby insurin g perfect action of the cutters.

The rear end, Y of the rocking part Yis kept in contact with the cam Qso that the action of thelatter may be imparted to said rocking partbymeansof a spiral spring, Qflsecured at one end to the under side of said.partY and at its other end to a stationary part, Q

.angle.

, The guide s may be adjusted in its supporting-bearing to differentangles by means of set-screw s.

The adjustable barb-wire rest s fljust in front of the stationary cutters, is also made with an inclined top surface, .9. (See Fig. 9.)

.Therefore when the barb-wire is fed forward over said rest 8 it lies atan angle to the stationary cutter s, as is also shown in Fig. 9, sothatwhen the movable cutting-edge u is passed .by it the wire is cutapart upon an angle, as

before stated.

The angle of the out 20 may be varied as de sired by changing the angleat which the wire is fed forward and the angles of thecutters.

The barb-wire rest 8 is held -in position by the holding part 8 which isformed or fastened on the inner end of a screw, .9 There- 'fore it maybe unfastened or fastened in adjusting the rest, as required. It may beadjusted vertically means of an adjusting screw, 8 upon which its lowerend rests. The angle of the top surface, 8 may be varied as required.

It will be seen that by this construction and arrangement the barb-wire00 maybe out close up to the coil 00 upon the main wire as, therebyadmitting of the barbs being made considerably shorter than by the useof similar machines'now in use, which is an important feature, inasmuchas it enables quite a saving in material, and therefore expense, in themanufacture of such fencing, while at the same time the utility of thefencing is improved, rather than impaired, by thusshortening the barbs,as they are less liable to be bent than the longer ones by stock rubbingagainst or coming in contact with the same.

The several parts of the machine are represented in the drawings in thepositions that they occupyjust after the barb-wire 00 has been fedforward under the main wire as, and prior,

to being coiled or wrapped about the same, as before described, by theturning-finger q.

The operation of the machine maybe briefly summed up thus: The mainwires 00 and 00 are first uncoiled from suitable reels or spoolsarranged at a convenient distance from the machine, then passed throughthe machine by hand and their ends fastened to one of the arms of thespool of the twister, which is not shown in the drawings, the samenotconstituting a. part of this invention. The wire as, after havingbeen passed through the opening ,3] of the guide Z and between its setof feed rolls R B, is then passed through a longitudinal opening formedin pinion W and wrapping-spindle'W", and thence over plate t and otherparts to the twisting-machine, as

aforesaid. The wire 00 after having been passed through the opening Y inthe guideZ and between the feed-rolls RE, is drawn forward over therocking part W, thence outside of the guide Zin front of the guide Z asshown in Fig. 2, and forward to the twister, as aforesaid. The barb-wireis first passed through the opening y of the guide Z and between thefeed-rolls T T, thence through the opening 1 in the inclined guide 8over the supporting part 8 under the main wire a), and over the barbcoiling or wrapping finger q, whereitis left. The machine is now turnedby hand and the firstbarb put on to get the machineingoodrunningcondition,when thepower is then applied,and the main wireszrarare fed barb is to be put on, and there stopped to allow the barb-wireto be fed forward by the rolls T T, said barb-wire coiled about the mainmanner before described, by a continuous and automatic operation. Themain wires are then again fed forward and the aforesaid operationrepeated. As fast as the barbs are fastened upon the main wire 00 andsaid wire :12 and wire 00 are fed forward they are in tertwisted to formone double strand,as represented atw Figs. 2, 11, and 12 of thedrawings, by a suitable twisting-machine provided for the purpose,arranged at a short distance from and in a line with the'bathing-machine, said twister also coiling the wires as fast as they areintertwisted upon a spool or reel arranged upon the same, ready for themarket.
